I have a WordPress blog that allows users to register. Each user will have their own profile page that has their picture and various information.

I'd like users to be able to subscribe to RSS feeds in the WordPress blog such as feeds from categories and tags by clicking a "follow" button. Then the feeds would automatically appear on the User's Profile page. Then I'd like the option for the users to be able to unsubscribe to the feeds (unfollow) so it stops appearing on their profile page if they want.

Is that possible? Can someone help me out with some code or a plugin? I looked everywhere and can't seem to figure out how to do this.
